ATTACHMENT FOR CULTIVATORS.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed July 11, 1911. Serial No. 637,965.

To all whom it may concern.

Be it known that I, FREDERICK BARZ, a citizen of the United States,residing at Ventura, in the county of Cerro Gordo, State of Iowa, haveinvented certain new and useful Improvements in Attachments forCultivators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to an attachment for cultivator-s and moreespecially to an attachment for a corn cultivator of the lid ing typehaving a double row of cultivators so as to operate upon both sides ofyoung cornstalks.

The specific object of the invention is to provide an attachment whichmay be socured to an ordinary frame of a cultivator of the above type soas to pick up the corn in windy weather or after a storm, when the cornis leaning across the rows, so as to prevent the wheels of thecultivator from running over the corn-stalks or leaves and thusdestroying the same.

Another object of the invention is to provide an attachment which may beapplied to cultivators of a common type and in which a pair of dependingarms are provided for engaging the stalks and directing the same to avertical position and in which said arms are capable of movement towardand away from the wheels of the cultivator to facilitate the raising ofthe stalks.

lVith the above and other objects in view the invention consists ofcertain other combinations and arrangements of parts as will behereinafter more fully described and claimed, it being a still furtherobject to provide a device which will not be likely to get out ofworking order.

In the drawings :Figure 1 is a top plan View of a cultivator with myimproved attachment applied thereto. Fig. 2 is a side elevation thereof,with the arms shown in dotted lines in their foremost and rearmostpositions. Fig. 3 is an enlarged detail showing the manner of connectingthe arms to the rocking bar to permit adjustment thereof upon the bar.

Referring to the drawings in detail, there is shown my improvedattachment applied to a straddle row wheeled cultivator which may be ofany ordinary or improved construction and which comprises an arched axle10 having oppositely extended spindle ends 11 upon which the supportingwheels 12 are journaled and adapted to straddle the rows of corn orplants during the cultivating operation. The cultivator is provided withthe usual cultivator beams 13 having the usual plows 14, all of whichmay be of any ordinary or preferred construction and a draft tongue 15extends rearwardly of the arch of the axle l0 and is rigidly secured bya frame structure 16.

The frame structure 16 has its side portions secured to the arch of theaxle and extends rearwardly of the wheels to support the drivers seat17, while the forward end of the frame has its side portions convergedtoward the tongue as shown at 18 and secured thereto. In theconstruction and application of my improved device for raising the cornstalks or leaves to a vertical position when cultivating the plants inWindy weather or after a storm and when the corn is leaning across therows, I provide a cross bar 19 which is secured transversely of thecultivator in front of the wheels 12 and mounted for pivotal or rockingmovement in bearings 20 formed or provided upon the sides of the framestructure 16 adjacent to the converging portions 18.

As shown in the drawings, the bar 19 extends beyond the sides of theframe and carries a pair of depending arms 21 which are curved forwardlyat their lower ends as shown at 22, said arms being sufficientlyresilient to pass over rocks or any other such obstruction, althoughthis is not likely to occur. 'lhese arms are positioned forwardly of thewheels and at their upper ends are provided with sleeve portions 23whereby the said arms may be moved longitudinally upon the bar toaccurately space the same apart in proper relation to engage the plantsaccording to their angle of inclination and the said arms may be held intheir adjusted position by suitable clamping members 24 engaged throughthe sleeve portions 23 for contact with the cross bar. The arms are thusheld rigid for movement with the cross bar and in order that they may beswung forwardly or rearwardly in the position shown in Fig. 2 of thedrawings, so as to properly engage the stalks during the travel of thecultivator along the rows of plants, an operating lever 25 extendslongitudinally of the tongue rearwardly of the cross bar and is adaptedfor sliding movement in a sleeve 26 secured to the tongue. The forwardends of the lever 25 is pivotally connected to the upper end of acentrally located and comparative-short arm 27 which is rigidly securedto the cross bar and the rear end of the lever is provided with agrasping member 28 in position for convenient operation by the driverfrom the seat 17. It will thus be seen that by sliding the lever withinthe sleeve 26, rocking movement is imparted to the cross bar within itsbearings so as to tilt the engaging arms to properly raise the stalk andleaves of the corn and in order to hold the lever in its adjustedposition, a series of notches 29, preferably three in number are adaptedfor engagement with the sleeve 26 at one edge thereof when moved todifferent positions. By having the lever connected to the cross barcentrally of its length, the arms are capable of movement very easilyand will be moved in unison to a common extent, thereby insuring properengagement with the plants.

From the foregoing description in con.- nection with the accompanyingdrawings, it will be seen that I have provided a simple and efficientdevice for the purpose intended which may be applied to cultivators ingeneral and which by reason of its extreme simplicity of constructioncan be economically manufactured.

I claim 1. In an attachment for cultivators, the combination with theframe structure thereof; of a tongue connected to the frame andextending centrally between the same to a point adjacent the rearportion thereof, a

seat mounted on the rear portion of the frame, said frame havingopposite bearing portions at its forward end, a shaft rotatablysupported therein and extending beyond the sides of the frame, dependingarms having sleeve portions loosely mounted on the extremities of theshaft, set screws operating through said-sleeve portions to engage theshaft and hold the arms in an adjusted position in their relation to theground and with each other, an arm extending upwardly from the centralportion of the shaft, a lever connected to the free end of the arm andextending rearwardly of the tongue and means carried by the tongue forengaging the lever and holding the same in an adjusted position.

2. In. an attachment for cultivators, the combination with a framestructure, tongue and wheels thereof; of a cross bar journaled upon theframe forwardly of the wheels, arms slidable on and depending from thebar adjacent its ends and immediately i11- side of the wheels, a leverconnected to the bar for rocking the same and extending along thetongue, said lever being provided with a plurality of notches and asleeve member carried by the tongue through which said lever operates,said sleeve being adapted to be engaged by the notches for stationingthe lever and holding the arms in an adjusted position.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
